Late on October 14, blogging directory and rankings site Technorati discontinued its Technorati Rankings and related data. ComMetrics used Technorati Ranking as part of its ComMetrics Footprint calculations.
Due to Technorati’s decision, we had to remove this measure from our ComMetrics Footprint.
Technorati Authority still exists, but now focuses much more on data from the last 30 days. The given Authority rank is somewhere between 1 – 1,000.
- Scoring factors that are considered in this metric are:
- posting frequency,
- context,
- linking behavior, and
- ‘other inputs’.
This results in more volatile score, since blogs can frequently move up or down on the 1 – 1,000 scale.
Technorati explained the decision in a recent blog post:
- “With the new algorithm, the resulting Authority will better reflect the fast-changing nature of the blogosphere. Its new inherent volatility will also show which blogs are rising and falling in authority, rewarding authors on posting frequency, context and linking behavior, as well as other data inputs.”
Currently, Technorati provides little, if any, information about how it calculates its Technorati Authority score for the blogs in the ranks. Furthermore, the Application Programming Interface (API) is still unavailable (difference between a widget and an API explained in plain English).
We have therefore removed Technorati rankings from our calculations, at least for now. We will consider re-introducing them as soon as Technorati again makes this feasible.

Well, even the most read and linked to German Blogs now have a Ranking of 1.
And neither Backlinks nor Content/recent posts are shown in Technorati.
So it has become 200% useless.
Bye, Technorati.

Thanks so much for your comment.
I wholeheartedly agree with your assessment.
I might even go a bit further and say that there are THREE main concerns with Technorati’s Authority ranking right now, namely:
a) If a blog is not registered in Technorati’s database, its link to your blog does not count.
b) Technorati does not explain in any way how it scores my blog giving it from 1 to 1000 points.
This score is somehow derived from the pingbacks/trackbacks or backlinks my blog is getting. These links should be no older than 30 days.
Of course, only those links from blogs registered in Technorati’s database count (i.e. owner registered his blog with Technorati in the past)..
c) How often Technorati visits these blogs to check for the links is anybody’s guess. Our crawlers indicate that Technorati’s crawlers are a bit erratic and unreliable (i.e. frequency between visits changes sometimes a few days sometimes 2 weeks or more).
CONCLUSION
Nobody can use a measure for any serious benchmarking, unless one understands how the benchmark figures are being calculated.
With Technorati, your guess is probably better than mine.

Oliver, of course you knew all that. However, I just wanted to state this to make sure all readers are on the same page as you and I.
Thanks for sharing.
